Agent Nintendo's Space Base is a secret and heavily protected hideout on the Moon, the natural satelite that orbits the Earth. The reason it is filled with advanced technology is because Agent Nintendo is from the future, so he knows perfectly how to make this stuff.
It was made due to the fact the Robber Penguin Agency was in need to have a security system and defense post in space that could not be inflitrated by any known 'hero' agency in Club Penguin. The base is also used as a place to store files and a meeting place. A maxinum of two prisoners can be held here.
